Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Analytical Chemistry (Washington, DC, United States) called Integrated nanoextraction and colorimetric reactions in surface nanodroplets for combinative analysis, Author is Wei, Zixiang; Li, Miaosi; Zeng, Hongbo; Zhang, Xuehua, which mentions a compound: 76-60-8, SMILESS is CC1=C(Br)C(O)=C(Br)C=C1C2(C3=CC(Br)=C(O)C(Br)=C3C)C4=CC=CC=C4S(O2)(=O)=O, Molecular C21H14Br4O5S, Recommanded Product: 76-60-8.
A combinative approach for chem. anal. makes it possible to distinguish a mixture of a large number of compounds from other mixtures in a single step. This work demonstrates a combinative anal. approach using surface nanodroplets for integrating nanoextn. and colorimetric reactions for the identification of multicomponent mixtures The model analytes are acidic compounds dissolved in an oil that are extracted into aqueous droplets on a solid substrate. The proton from acid dissociation reacts with the halochromic chem. compounds inside the droplets, leading to the color change of the droplets. The rate of the colorimetric reaction exhibits certain specificity for the acid type, distinguishing acid mixtures with the same pH value. The underlying principle is that the acid transport rate is associated with the partition coefficient and the dissociation constant of the acid, as well as to the concentration in the oil. As a demonstration, we showed that droplet-based combinative anal. can be applied for anti-counterfeiting of various alc. spirits by comparing the decoloration time of organic acid mixtures in the spirits. The readout can be done by a common hand-hold mobile phone.
